In software engineering, double dispatch is a special form of multiple dispatch, and a mechanism that dispatches a function call to different concrete functions depending on the runtime types of two objects involved in the call. In most object-oriented systems, the concrete function that is called from a function call in the code depends on the dynamic type of a single object and therefore they are known as single dispatch calls, or simply virtual function calls.

Famous quotes containing the word double:
“To be a woman and a writer
is double mischief, for
the world will slight her
who slights “the servile house,” and who would rather
make odes than beds.”
—Dilys Laing (1906–1960)
